FREE stuff anyone?

Today I watched a TV advert for Argos - FREE £5 gift card when you spend £50, FREE £10 gift card when you spend £100. Great offers I thought, you could even give the FREE gift card as a Christmas stocking filler. Great marketing idea, really grabbed my attention and I'm sure the attention of many thousands of other viewers. Look more closely and you see what you are really getting is a 10% discount (at most). If you spend £60 or £70 the discount falls further. The point: people love FREE, it's a powerful word and giving the FREE gift card is far more attractive than simply saying, "save 10% today". Look at your business, could you offer something similar? This is a great way to boost sales. It works for the big retailers, so well they can afford to spend thousands on TV ads promoting the offer.
